The Secret of Surnames...from a village near Patna

A guy from Bihar was away from his family for about 4 years
while his wife was in a village near Patna. At the end of 4 years he distributed
sweets to his colleagues in office stating that his wife had delivered a
son............
His colleagues were quite shocked and they asked how this "happy event"
happened when he had not seen his wife for four years... The man said it is
common in Bihar that neighbors take care of the wife (good Samaritans) when men
are away.The colleagues asked him," What name will you give to the son?
"The man explained, " If its the second neighbor who has taken care, then
the name would be DWIVEDI;
If it is the third neighbor then it would be TRIVEDI,
If it is the fourth neighbor then it would be CHATURVEDI;
If it's the fifth neighbor then it would be PANDEY...
After listening to this, questions followed. What if it is a mixture of
neighbors? "Then the boy would be named MISHRA"...
And what if the wife is too shy to tell the name of the neighbor? "Then it
would be SHARMA"...
But what if she refuses to divulge the name of the neighbor? "Then the name
of the child would be GUPT-A"...
If she does not remember the name then? "It is YAAD-AV..."
But who knows whether the child resulted from a rape? "Then it will be named
DOSHI"...
Finally, if the child happened because of wife's burning desire for sex?
"Then he will be named JOSHI...
